THAUMATIN FROM THAUMATOCOCCUS DANIELLII

Uses

Thaumatin from Thaumatococcus daniellii has been used:

• as a positive control/standard to detect the amount of recombinant thaumatin in the milk of transgenic mice using western blot
• as a standard to compare its retention time with Vitis vinifera thaumatin-like proteins (VVTL1) occurring in free-run juice and determine the pathogenesis-related protein content in grape juices
• as a model protein to study its interaction with free and ligated decavanadate

Biochem/physiol Actions

Recently it was shown the over expression of the thaumatin gene from Thaumatococcus daniellii in tomatoes caused the fruit to have a sweeter taste, suggesting that thaumatin could be used to enhance the taste of various foods.
